Origin of water on Earth

Earth is unique among known planets in having oceans of liquid water on its surface. It was long thought that Earth's water did not originate from the planet's region of the protoplanetary disk. Instead, it was hypothesized that water and other volatiles must have been delivered to Earth from the outer Solar System later in its history. Recent research…
